Backup of Hudson Config for Building Crackpot

Some time before I set up Hudson for continuous integration of Crackpot. Here I want to back up all the configurations for ready reference (physical backup of Hudson home dir is already set).

• Dependencies for Building
• Config for Building Crackpot
• Hudson Settings
• Setting Hudson as a Service

Dependencies for Building

• Visual Studio for devenv
• cmake
• cygwin to execute shell

Config for Building Crackpot

Under Build > Execute Shell, put:

  # define build and installation directories
   BUILD_DIR=$WORKSPACE/crackpot_root_dir/build
   SOURCE_DIR=$WORKSPACE/crackpot_root_dir

   # we want to have a clean build
   cd "$BUILD_DIR"

   # initializing the build system
   cmake  -G "Visual Studio 9 2008" "$SOURCE_DIR"

   # fire-up the compiler
   # NOTE: put denenv in system path
   devenv.com Crackpot.sln /clean Debug /project ALL_BUILD
   devenv.com Crackpot.sln /build Debug /project ALL_BUILD
   devenv.com Crackpot.sln /build Debug /project RUN_TESTS

  # define source directories
   SOURCE_DIR=$WORKSPACE/crackpot_root_dir

   # we want to have a clean build
   cd "$SOURCE_DIR"

   doxygen

Hudson Settings

Environment Variables: 

key: PATH
value: %PATH%;C:\Program Files\CMake 2.6\bin;C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE;C:\Windows\System32;C:\Program Files\doxygen\bin

Shell executable:

C:\cygwin\bin\sh.exe

Setting Hudson as a Service

There was some issue with using the Hudson built-in way to set as service. I followed this and this.

Process Getting Killed Using Ubuntu 10.04 as VMWare Guest OS

I installed our memory-intensive software on Ubuntu running on VMWare. This process was getting killed quite quickly after start. After some internet search, I understood that this is due to the OOM-killer in the kernel. To disable to OOM-killer, I added to my /etc/sysctl.conf:

vm.oom-kill = 0 

I got this and a lot of other useful information related to oom-killer from this forum. But most of what is said there regarding oom-killer configurations does not apply to Ubuntu 10.04.

Using SVN Externals to work with Multiple Repositories

I am writing a library called HSL. This library will be a third-party library in Crackpot and used for encoding heuristics. In order to work with Crackpot code along with HSL, I will be using the "svn externals" mechanism.

http://svnbook.red-bean.com/en/1.5/svn.advanced.externals.html

Why not simply have a copy of the external library in local repository? The primary benefit is that changes made to the local copy can be committed to the external repository.


Mechanism:

~/tmp/co$ svn propedit svn:externals .
No changes to property 'svn:externals' on '.'
~/tmp/co$ svn propget svn:externals .
thirdparty/hsl/hsl_alpha_version  -r5 https://heuristic-selection-library.googlecode.com/svn/trunk

~/tmp/co$ tree
.
`-- thirdparty
    `-- hsl
        `-- hsl_alpha_version
            `hsl



Problems:

• More complex "svn stat" output: http://stackoverflow.com/questions/2789344/dont-show-svnexternals-in-svn-status
• Changes made to external repository using the local copy must be explicitly synced with the svn:externals property values.
